Embodiment Construction

[0034] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0035] This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, components are exaggerated for clarity.

[0036] Such as figure 1 As shown, the present invention discloses a non-invasive parafoil steering rope tension sensor, including first to second elastic beams, first to third fixing components, and first to fourth strain gauges;

[0037]The first elastic beam and the second elastic beam are cuboids with the same structure, and both include a first end wall, a second end wall, and first to fourth side walls connected end to end, wherein the first side wall is parallel to the first Th...

Abstract

The invention discloses a non-intrusive parafoil control rope tension sensor, comprising two elastic beams, three fixing assemblies and four strain gauges, wherein each elastic beam is overall in a cuboid shape, and three countersunk through holes, an H-shaped through groove, two trapezoidal grooves and two force balance grooves are formed in the elastic beam; and each fixing assembly comprises a screw, a sleeve and a nut. By adopting a split structure, the sensor can be conveniently mounted and dismounted on a parafoil control rope, and a side pressure type non-invasive design has no damage to the structure of the control rope; the layout of the same elastic beams on the two sides enables stress to be uniform, so measurement accuracy is improved; and while a requirement on the measuring range of the control rope tension is met, the sensor is small in overall size and light in weight, and the sensor better meets working requirements under a parafoil flying condition and solves the problem that the parafoil control rope tension is difficult to measure in real time.

Description

technical field [0001] The invention relates to the technical field of sensor non-destructive measurement, in particular to a non-invasive parafoil steering rope tension sensor. Background technique [0002] The control rope is the control rope used in the parafoil system to adjust the flying speed and flight direction of the parafoil (two in total, one on the left and one on the left). It is still a sparrow drop, and it is an important part of the parafoil research to explore the influence of the force change of the control rope on the parafoil control during the parafoil glide process. Therefore, in the research and design process of the parafoil, it is necessary to monitor and measure the force change of the parafoil during the flight process of the parafoil, and judge the relationship between the control force input and the response of the parafoil, so as to determine the control force of the parafoil landing, Control speed and control timing, etc. [0003] There are d...
